MASSAGE APPARATUS.

Application filed August 8, 1911. Serial N 0. 642,935.

rocking motion is imparted to the tool or implement which effects the massaging or tapping treatment. Such instruments have been provided with protecting cups, arms or devices, but such protectors have only been provided in connection with single armed tools having a single tappingaction whereas the object of my invention is to provlde a tapping tool with which instead .of the ordinary single tapping or vibratory effect, an

alternating double tapping effect is produced, that is to say the rocking member 1s rocked so that two tools or tapping surfaces are alternately brought into operation, pref- T erably symmetrically on either side of the longitudinal axis of the instrument, guides or protecting surfaces being provided at either side or around the tool or tools or surfaces. I may also provide means for adjusting in an easy manner, the extent of the rocking motion.

In the accompanying drawings an instrument with my present improvements is illustrated, Figure 1 being a'longitudinal section of the implement; Fig. 2 being a plan.

view thereof; Fig. 3 a longitudinal section taken at right angles to Fig. l.

The instrument comprises a suitable casing or frame a in which is arranged the gearing for imparting motion to the tool or tapping device. This gearing may be of any suitable description and is here shown as hand driven and consisting of a handle I) shaft 0 and multiplying pinions (Z, d, (Z d The latter is mounted upon a shaft 6 upon which is also provided an eccentric or cam f working in a corresponding passage or recess in the end of a sleeve 9 in which the rod or stem 9 of a pivoted member 9 is arranged in such manner that the two parts 9 can have a slight telescopic motion when the sleeve g is rocked by the eccentric. These parts 9 g constitute the rocking member which is pivoted about an axle g mounted in the casing a.

Patented Mar. 28,1916:

7 The top of the rockingmember is formed or provided with a tapping tool or surface it, herein shown as a plate secured centrally to the rocking member and having its sides substantially level with the top of the casing a or of guides '2' secured thereto. The operative surfaces of the tool, which is preferably removable and adjustable, can be,-as shown, flat'or substantially flat plates, orthe tool may consist of a forked lever, carrying balls or other operative surfaces which may be ad.-. justable at its free ends,- symmetrica'lly arranged on either side of the center, and mounted in a suitable manner on the rocking member. A hole 9* can also be provided in this member to receive the stem of a suitable frictional tool, such as a ball.

It will be observed that the tapping plate 72, consists of a strip of metal having a central transverse channel whereby it is secured to the rocking member. This is a very'efficient form of tapping member since the arms or wings oneither side can be some- 1 what springy and this contributes to the vibratory nature of the tool.

On either side of the tapping member h I arrange protective and support plates '71, here shown as metal plates screwed to the sides of the casingand having outwardly eX- tending flanges z" substantially, level with the outer surface of the tapping tool. These guides in the first place protect the tapping tool from accidental injury while they also prevent the latter. from being pressed with such force against the patient as to stop the action of the tool. Obviously the protecting device or devices could extend completely around the tool if being, as stated, to prevent the tool being pressed too forcibly against the part being operated upon. In those cases where the protecting devices are not integral parts of the casing or frame they must be adjustable and removable.

It will be readily understood that when the handle b is turned the shaft 6 will be rapijplly rotated, causing, through the eccentric 9 thereby causing the arms of the tool it to give alternate strokes against the part to which the tool is applied. a

While the method illustrated in Figs. 1 and 3 of effecting the'rocking. motion of the tool is a suitable vone it can be effected in desired, the main object I the member 9 g to rock about its pivot W'hileI have described the instriinient as I being provided with means for operating the tool byhand, it will be evident that it"ca'n be driven electrically .or. mechanically. 1
